Here, a simple post concerning the Administration Methods. what are Administration Methods ? which are Administration Methods ?

Administrative methods are methods that perform a variety of administrative and monitoring tasks. They are executed in an application by invoking either the DQL EXECUTE statement or the IDfSession.apply method. You can also execute them interactively through Documentum Administrator.

Invoking administration methods via DA
To execute an administration method manually, use Documentum Administrator in the node (Administration/Job Management/Administration Methods). All the methods (except DO_METHOD, WEBCACHE_PUBLISH, and ROLES_FOR_USER) are available through the Methods facility in repository Management. Many of the methods are also available through category-specific pages.
Note: Because DO_METHOD is used to execute user-defined procedures, this method is implemented as part of the Attributes page for user-defined methods.

Invoking administration methods via DQL
To execute an administration method in an application, use the DQL EXECUTE statement. You can also use EXECUTE to invoke an administration method through IDQL.
The EXECUTE statement is the DQL equivalent of the API Apply method. You can use it to execute any of the administration methods except PING or WEBCACHE_PUBLISH.
The EXECUTE statement is not case sensitive. You can enter the administration method name and argument names in uppercase, lowercase, or any combination. You must enclose character string values (including an object ID in a FOR clause) in single quotes when they are included in the EXECUTE statement.

Note : It’s possible to use IDQL32.exe or IAPI32.exe in order to execute DQL or API commands. The scheduling could be done via OS tasks (like Windows Scheduled).

Some examples….:DO_METHODExecutes an external program, a Docbasic script, or a Java method. (Note that use of Docbasic is deprecated.)

Invoking administration methods via API with APPLY instruction
To execute an administration method in an application, use the specific API instruction APPLY. You can also use these instructions through IAPI. The API Apply method is the API equivalent of the DQL EXECUTE statement. The Apply method returns a collection identifier for a collection that contains the results of the specified method.

Note : It’s possible to use IDQL32.exe or IAPI32.exe in order to execute DQL or API commands. The scheduling could be done via OS tasks (like Windows Scheduled).

Some examples….:GET_PATHReturns the directory location of a content file stored in a distributed storage area.

Invoking administration methods via DFC – getSession().apply(…)
To execute an administration method in an application, use the IDfSession.apply method. For information about using IDfSession.apply to invoke an administration method, refer to the Javadocs.

Note : It’s possible to include this code in a custom job executed by dm_agent_exec.
